IMPROVEMENT IN ANTI-FRICTION JOURNAL-BEARINGS.

Specification forming part of Letters Patent No. 212,744, dated February25, 1879 application filed January 15, 187 9.

To all whom "it may concern:

Be it known that I, LORENZO RANK, of Oswego, in the county of Kendalland State of Illinois, have invented a new and valuable Improvement inAnti-Friction Roller-Bearings; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a longitudinal centralsection of my invention; and Figs. 2, 3, and 4: are details.

This invention has relation to improvements in anti-friction bearingsfor vehicle-axles; and the nature of the invention consists incombining, with an axle-arm and a hub, large rollers interposed betweenthe journal and box, smaller rollers between the said large rollers, andshouldered to hold them in place, collars applied upon the axle at eachend of the small rollers and anuularly grooved to receive the endsthereof, retainer-rings on the axle-arm at each end of the hub, andrings between the retainer and grooved rings, having spaced perforationsand balls in said perforations, as will be hereinafter more fully setforth.

In the annexed drawings, the letter A designates the spindle of avehicle-axle, separated from the body thereof by a collar or shoulder,(1, and B designates the wheel-hub. (I11- dicated by dotted lines, Fig.1.)

Bearing respectively against the shoulder a and nut 12 are rings 0 O,the former being at the inner, and the latter at the outer, end of thehub, as shown in Fig. 1. These rings usually turn loosely around theaxle-arm, but may be fixed thereto, if I so elect.

Inside of rings 0 G are other rings, D D, and inside of the latter arestill other rings, E E. These latter are provided with annular groovesc, in which are received the ends of small rollers F, having theenlarged shoulders 01.

Between the rollers F are arranged the large rollers G, of sufficientdiameter to com- As shown in Fig. 4, the rollers F and G alternate witheach other, and completely in close the journal A, the perimeters of therollers G being tangential to that of the journal and to those of thesmaller rollers F. The

- ends of these rollers F being in the grooves c of rings E E, and theirshoulders (I holding the large rollers G against endwise displacement,these rollers are incapable of be ing disarranged relative to each otheror to the journal.

The middle rings, D D, above mentioned, are provided with holes 0 atregular intervals, in which are placed the balls f. Their diann eter isslightly greater than the thickness of the rings D D aforesaidconsequently they project at each side thereof, and afford a roll ingbearing to the rings E E, by which means end friction is reduced to aminimum.

The device above mentioned is secured in.

place by the nut 12. In its essential parts it is applicable to allsorts of journals and ro tating machinery of suitable size to greatadvantage.

I am aware that a rolling support for ma chinejournals is not new; henceI make no claim to such invention, broadly.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the journal A and hub B, of the rings E E,having annular grooves c, the small rollers F, having end shoulders, (I,and their ends engaged in said grooves, and the intermediate largerollers, G, between the said shoulders, tangential to rollers F, thehub, and journal, substantially as specified. v

2. The combination, with the journal A and the end rings, 0 O, the innergrooved rings, E E, and the intermediate perforated rings,

D D, and balls f, of the small rollers F, having end shoulders, 01, andjournalsengaged in' In testimony that I claim the above I have hereuntosubsoribed'my name in the presence of two witnesses.

LORENZO RANK.
